BACKGROUNDLightbulbs typically include threads around a neck for threading into a socket. The threads retain the lightbulb within the socket and allow insertion and removal of the lightbulb by rotation and counter-rotation, respectively.
SUMMARYAccording to an embodiment, a threadless magnetic lightbulb and socket system is provided. The system includes a lightbulb base having a neck with a threadless exterior surface, a socket having a receptacle with a threadless interior surface configured to receive the neck, and a first magnet positioned at a tip of the lightbulb base. The system further includes a second magnet positioned in the receptacle of the socket such that the first magnet and the second magnet are configured to attract each other to magnetically retain the lightbulb within the socket.
According to another embodiment, a threadless magnetic lightbulb is provided. The threadless magnetic lightbulb includes a lightbulb base having a neck with a threadless exterior surface and a magnet positioned at a tip of the lightbulb base.
According to yet another embodiment, a threadless magnetic socket is provided. The threadless magnetic socket has a receptacle with a threadless interior surface configured to receive a lightbulb base and a magnet positioned in the receptacle of the socket.
First and second magnets 120, 130 are examples of a permanent magnet that produces a magnetic field, which pulls on other ferromagnetic materials such as iron, and attracts or repels other magnets. In an embodiment, first and second magnets 120, 130 are compact high-strength magnets made from rare Earth elements, such as a neodymium-iron-boron magnet. First magnet 120 is configured to magnetically attract second magnet 130 towards first magnet 120 as depicted by arrow 161. Likewise, second magnet 130 is configured to magnetically attract first magnet 120 towards second magnet 130 as depicted by arrow 162. In other words, first and second magnets 120, 130 are arranged with the north pole of one magnet aligned with the south pole of the other magnet to attract each other. First and second magnets 120, 130 attract each other to magnetically retain threadless lightbulb 150 within threadless socket 110 without overlapping threads therebetween. The magnetic attraction is for example strong enough to prevent threadless lightbulb 150 from falling due to its weight when arranged beneath threadless socket 110 with respect to gravity.
A direct electrical connection 115 connects first electrical contact 112, located within the receptacle of threadless socket 110, with a second electrical contact 140 of threadless lightbulb 150 by direct contact (see

Magnet 320, which is an example of first magnet 120 of
Systems 100, 200 and 300 enable changing of a lightbulb without rotation of the lightbulb into and out of a socket containing threads. Advantages include less time to replace the lightbulb and less user dexterity needed to change the lightbulb.
